The Des Moines Register Political Soapbox returns to the Iowa State Fair Aug. 9 through 19 with more than two dozen state and national political figures scheduled to appear.

A long-running tradition in Iowa politics, the Soapbox this year features candidates running for Congress, governor, secretary of state, secretary of agriculture, auditor and treasurer. And, because it's Iowa, politicians both planning and considering 2020 presidential bids also are scheduled to speak.

The speeches will be held along the Grand Concourse in front of the Horner Service Center. Dates and times are subject to change, and more speakers may be added.
